Detection engineering with a catalog you can read and change

ThirdEYE loads 1,396 detection rules, 103 written for the platform and 1,293 imported from the open Sigma project, and lets your team add its own.

The problem

Rule coverage takes years to build

Starting from nothing leaves gaps that attackers find first.

Alerts arrive one at a time

Single events rarely show a multi-stage attack unless they are linked.

Nobody knows which rules are noisy

Without feedback on false positives, tuning is guesswork.

How ThirdEYE addresses it

  1. Start from a catalog

    Built-in rules and the imported Sigma catalog load together; built-in rules win ties.

  2. Build and tune your own

    A visual rule builder creates custom rules, mapped to MITRE ATT&CK techniques.

  3. Correlate across alerts

    The correlation engine links alerts by shared source, technique, asset and time window and tracks kill-chain progression.

  4. Learn from outcomes

    Investigation results and analyst feedback feed quality views such as false-positive rate per detection source.

Key capabilities and their status

Status labels reflect what is in the product today.

Available

Detection rule catalog: 103 built-in plus 1,293 imported Sigma rules

The catalog holds 1,396 rules (103 hand-written and 1,293 imported from the Sigma project) with a visual builder for custom rules.

Note: The visual rule builder is a UI feature without a dedicated backend test. Sigma rules belong to their authors under the Detection Rule License 1.1 and must be attributed. Counted by loading the catalog.

Available

Behavioural correlation and kill-chain progression

Correlates related alerts (shared source, technique, asset, time window) and tracks multi-stage progression.

Available

MITRE ATT&CK mapping and navigator

Alerts are mapped to ATT&CK techniques and tactics, with a technique drilldown.

Available

UEBA statistical anomaly scoring

Statistical (not LLM-based) anomaly scoring on user and host activity feeds the same alert pipeline.

Available

Similar past incidents memory

Completed investigations are stored in a tenant-scoped semantic memory and searched for similar history.

Where it fits in your environment

Sigma rules are authored by the SigmaHQ community and distributed under the Detection Rule License 1.1. ThirdEYE keeps their attribution with the catalog.

Catalog size is a count of rules loaded by the product, not a measure of detection coverage.

Scope to know about

  • Rule count is not coverage. Effectiveness depends on your log sources and tuning.
  • In the default Security AI configuration only high and critical alerts go through rule-based resolution, and Sigma-based resolution is off until enabled.
  • The catalog has not been independently benchmarked.
